Need to randomize multi-stacked points

Hannah_Hutchins — Wed, 29 Sep 2021 14:07:09 GMT

I have a very large point dataset (~35,000 points) that was created through geocoding. Roughly 40% of these points are multi-stacked. I'm looking for a way to separate these points from each other within a 10 foot radius.

Is there an automated way or a code I can use to randomize/distribute these existing points within a 10 ft buffer? I'm not looking to use the Create Random Points tool as my data is already created.

I'm working in ArcGIS Pro 10.7.1.

35 K dispersed within 10 ft is probably going to look like a smudge, anyway, have you seen

I am looking to do the same thing as Hannah. I need to move the actual points that are stacked on top of each other (not the symbols). I found the CountOverlappingFeatures tool in Pro that lets me identify how many points are stacked on top of each other at a specific locations (https://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/count-overlapping-features.htm#:~:text=Parameters%20%20%20Label%20%20%20Explanation%20,records%20for%20%20...%20%20%20Table%20). It gives me a point layer showing where the overlaps are. This is helpful but I still need a tool or method to move those points by a few feet so they aren't stacked/overlapping. I would really like to do this within a 10 ft radius like Hannah talked about above. Thanks!

After many days of digging, the only solution was the Disperse Markers tool which seemed to work for me. But if anyone else has insight, I would love to hear about it!

Thanks for the tip Hannah, I will try that. I've been searching GeoNet and just the internet in general but haven't found anything. All I see is information about moving the symbols, not the points themselves.

Perhaps if Dispersed Markers was the correct answer, you could mark as Accepted the referencing thread so it can be closed

The Dispersed Markers tool won't work for what I need but if it worked for Hannah, then I guess she can mark it as accepted. I have FME, I might see if it has a tool for doing what I need.

Perhaps you need Dynamic Feature Clustering instead

It may solve your problems if aggregation is ok

Thanks for the idea but I need to move the actual points not the symbols. I have a bunch of points that are locations of street signs. Many of these are stacked on top of each other, in some places, there are as many as 5 on top of each other. I would love a tooth or script that would allow me to make small circle polygons around those locations and then have a tool that would randomly scatter the points within those circles. Then I wouldn't have any more overlapping points. If I can't find a way to do this, I'll have to move them manually which will take a while...
